InGaAs Photodetectors at a Crossroads: Where Is the Industry Heading? Indium Gallium Arsenide (InGaAs) photodetectors have long been a cornerstone technology in near-infrared (NIR) and short-wave infrared (SWIR) detection. With their excellent sensitivity, low noise, and fast response, InGaAs photodiodes are widely used in applications ranging from optical communication and spectroscopy to military surveillance and LiDAR. However, as emerging technologies advance...
